Manchester United squeezed through to the Carabao Cup fourth round, 5-3 on penalties, Daniel James confidently dispatching the clincher on a night when Rochdale gave Ole Gunnar Solskjær’s men an almighty scare.Yet the result should not mask the latest worrying display, one that followed Saturday’s defeat at West Ham, as they were taken to spot-kicks by a 16-year-old right-back named Luke Matheson. He will long remember his 76th-minute equaliser and sprint to celebrate in front of the Rochdale fans he had sent into ecstasy.
